I’m unclear on exactly how V-Piano and SuperNatural stack up. IIRC, there were one or more top-end “V-Piano” products, but SuperNatural seemed to show up in more synthy products.
I lost interest because even PianoTeq doesn’t seem to allow Cage-levels of “preparation”, and multisampled pianos generally sound good enough to my ears.
Hopefully there are Elektronauts who have more experience with V-Piano or SuperNatural pianos that can help clear things up.
I know I can get a nice Casio digital piano with a decent hammer-action keybed for about $1k. I think if I was going to get serious about learning to play keys by taking piano lessons I might prefer to spend $2k on the Roland 08 to get the sequencer, sampler, much deeper instrument models, and of course all of the classic Roland samples, patches and sound design tools.
